Benefits of technology
[0014]Another advantage of the present invention is that additional couplings, such as extension couplings, do not need to be utilized, thereby eliminating points of potential leakage.
[0015]Still another advantage of the present invention is that the method of replacing the pipe coupling of the present invention is less time consuming and difficult than the previous method requiring the introduction of pipe extensions and additional couplings.
[0016]These and other objects and advantages of the present invention will be apparent to those skilled in the art from the following detailed description taken in conjunction with the drawings.BRIEF DESCRIPTION OF THE FIGURES

Problems solved by technology
However, as with all types of pipes, PVC and brass couplings will occasionally crack and need to be replaced.
Unfortunately, repairing or replacing a pipe coupling can be difficult and time consuming.
In addition, the replacement of the elbow joint coupling is extremely time consuming and mistakes are prone to happen in the extension of the pipe ends which must be measured relatively accurately for installation of the replacement elbow couplings.

Embodiment Construction
[0039]While the present invention is susceptible of embodiment in various forms, as shown in the drawings, hereinafter will be described the presently preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the invention, and the present disclosure is not intended to limit the invention to specific embodiments illustrated.
[0040]With reference to FIGS. 1-22, the present invention is directed to a method of replacing a coupling 1 which may need to be replaced for a variety of reasons such as a crack or leak as illustrated in FIGS. 15, 19 and 21. The method of replacing the coupling 1 entails cutting the pipe 15 adjacent to the coupling's extremities using a handsaw, electric saw, rotating pipe cutting tool or the like as can be selected by those skilled in the art. Once the pipe ends have been cut, the coupling 1 can be manually removed. Unfortunately, this leaves the pipes' length less than prior to remova...

A method of replacing pipe couplings is provided. The couplings, such as elbow joints, “T” couplings, “Y” couplings, etc., have a traditional conduit construction including tubular end sections which telescopically connect to pipe ends. The couplings are removed by cutting the pipes adjacent to the couplings tubular sections so that the pipes have a reduced length. A replacement coupling is connected to the pipe ends. The replacement coupling has tubular sections which are extended to have an increased length “L”. The increased length allows the replacement coupling to mate to the respective pipes even though the pipes have a shortened length than prior to removal of the replaced coupling.
Description
BACKGROUND OF THE INVENTION[0001]The present invention relates to methods and constructions for repairing pipe joints. More particularly, the present invention relates to a method of replacing preexisting couplings within a pipe joint.[0002]For both brass and polyvinylchloride (PVC) piping, it is common to form a pipe joint by inserting the male pipe ends into the female openings in a joint coupling. Once the pipe ends are telescopically received within the coupling, the pipes are adhered to the coupling by use of various methods including the use of welding and adhesive compounds. As examples only, PVC pipe joints typically utilize liquid adhesives to adhere the PVC coupling to the respective pipe ends. Conversely, brass fittings are typically adhered in place using conventional welding methods. More recently, couplings affix to pipe ends using press-fit configurations in combination with O-rings and mechanical locking flanges.[0003]Forming an initial pipe joint is relatively uncom...
